Riot is an Australian Shepherd. The dog at one point was hit by the Impala. Sam, realizing this, rushes the dog to the veterinary hospital, where the dog gets treated by a vet named Amelia. Sam later accepts his responsibility for the dog, and agrees to take care of him. It is now assumed, after Sam left Amelia, that she is now the caretaker of Riot.
Sam remembers when he hit Riot with the Impala. He rushed him to a veterinary hospital, where Amelia is the vet who tends him. Riot sustains some serious internal bleeding and at least two leg fractures. Amelia tells Sam the dog has no owners, and points out his responsibility for the dog, and so Sam agrees to take care of him.
At the motel, Sam has Everett run a new credit card and comments that Riot, who he doesn't yet have a name for and just calls "Dog," has a surgery follow up on Tuesday.
Sam remembers how Riot leads him into Amelia's motel room, which he doesn't want as she thinks he's creepy. However, Amelia calmly pets Riot and they discuss how Riot is recovering well and Sam compliments how skillfully she stitched him up.
Riot appears in a flashback when Lucifer tries to convince Sam to say yes and take him as a vessel. Riot is next to Sam and Amelia Richardson who appear to be discussing Don Richardson's sudden return to Amelia's life after she believed that he was dead.
